Designer and amateur dancer Lesia Trubat has created a new type of ballet shoe for the high-tech ballerina. Electronic Traces records the foot’s contact with the floor, allowing the dancer to “draw” all of their movements in brush-like strokes.
“E-Traces,” as it is known, starts with a small electronic device affixed to the bottom or side of a dancer’s shoe. The sensors come from Lilypad Arduinos, which can be purchased online and has been used for all kinds of different wearable electronics.
Trubat wove the wires and circuits into the soles of the shoes, and the hardware detects the pressure on the shoe as well as the force of motion from the dancer. A computer program then translates the data and sends it to a custom mobile app program. The result is a beautiful constellation of delicate “paint” marks that look almost as graceful as the dancers themselves.
The ballet shoes were designed by Trubat as a degree project for ELISAVA design school in Barcelona, Spain.

The Milker Corporation's Jennifer Walshe is running a free text score service via the mobile app Snapchat. THMOTES is the name of Walshe's app d'art. The real-time picture chatting scores will exist for ca. 7 seconds before, as The Wire says, "vanishing into the ether."
